Microwave heating mechanism and Self-healing performance of scrap tire pyrolysis carbon black modified bitumen

Conventional asphalt mixture has poor microwave absorbing performance and microwave heating efficiency. Based on the characteristics of dielectric loss of scrap tire pyrolysis carbon black (PCB), it is proposed to improve the microwave absorbing performance and self-healing rate of bitumen. The phase composition and electromagnetic parameters...

Investigating the High- And Low-Temperature Performance of Warm Crumb Rubber-Modified Bituminous Binders Using Rheological Tests

Rubberized asphaltic materials have been frequently combined with warm-mix asphalt technologies to tackle the issues of high energy consumptions and emissions during construction. Effective and accurate characterization of binder properties is conducive to the improvement of long-term pavement performance. The current study aims to quantify...

Characterization of bitumen modified with pyrolytic carbon black from scrap tires

Pyrolytic carbon black (CB _p ) from scrap tire pyrolysis is a potential modifier for the bitumen industry. Binders containing different contents of CB _p were prepared and experimentally investigated to examine the effects of CB _p on the electrical and thermal conductivity, conventional physical properties,...

Non-Newtonian behaviors of crumb rubber-modified bituminous binders

Crumb rubber-modified bitumen (CRMB) has been utilized in the asphalt paving industry for decades due to its various benefits. The complex interaction between bitumen and crumb rubber as well as the addition of warm-mix additives makes the typical laws of Newtonian fluids insufficient to describe the behaviors of highly modified bituminous...
